Temat 10: Forces and Motion

Forces and Motion - REVISION PODCAST

This revision podcast is for Edexcel IGCSE physics (4PH0 or 4SC0), and covers all of topic 1 - forces and motion. It is also suitable for other GCSEs.
There's no hard and fast rule about what to plot on each axis of a graph - I have plotted Force on the y-axis and Extension on the x-axis so that the gradient of the graph is k - the spring constant. (Consider the equation F=kx and the general equation for a straight line, y=mx).
I know that generally, students at GCSE are taught that the independent variable (what you change) goes on the x-axis, and the dependent variable (what you measure) goes on the y-axis, but sometimes it dies make sense to swap the axes, if the gradient is more meaningful.
